Wonder if the label shown on FB or wherever is the new "real" label, as the old 90 proof label does not have the "(ninety proof)" as the bottom line.
Every bottle I've ever had has "ninety proof" written out. I actually commented that the lower-proof bottling does not spell out "eighty-four proof" at all. It just says "Alcohol 42% by volume". (However, I mistakenly thought the 90 proof bottling doesn't say "Alcohol 45% by volume". It does.)
